How does Touch ID work on your iPhone 7?

New models of iPad and iPhone devices integrate a capacitive Touch ID sensor in the Home button. To detect your finger or fingerprint, the Touch ID utilizes a color-matched steel ring that surrounds the sapphire glass lens. This highly scratch-resistant sapphire glass lens protects that assembly and focuses the sensor and the steel ring. The capacitive Touch ID sensor activates when the ring is triggered. It then takes a high-resolution snapshot of your fingerprint. The new fingerprint input is compared with the ones stored in the secure domain on the processor. If they match, Touch ID will instantly authenticate access and unlock the iPhone. Purchases and access to certain apps are also authenticated and authorized. But if the fingerprints don’t match, Touch ID does the opposite or denies access to the device.

Touch ID uses the data it acquires every time it it scans your fingerprint. These data will be used to improve recognition for it to work more consistently from more angles over time.

How to get started?

Just like other iPhone features, Touch ID needs to be set up before you can use it on your device. Here’s how:

 

  • In order to get started, you will need to set up Touch ID on your iPhone 7. You will need the passcode for your device before you can proceed with the Touch ID setup. If necessary, create or set a passcode on your iPhone 7 by going to Settings-> Touch ID & Passcode-> then tap the option to Turn Passcode On. Proceed by entering a six-digit passcode or tap Passcode Options to switch to a four-digit numeric code. You can set a custom numeric code or a custom alphanumeric code for your passcode. Enter the same passcode again to confirm and activate it.

 

Once the passcode is set up, proceed with the subsequent steps to set up Touch ID:

 

  • Tap Settings.
  • Select Touch ID & Passcode.
  • Enter your passcode.
  • Tap the option to Add a Fingerprint.
  • Hold your iPhone as you normally would while touching the Home button with your finger.
  • Be sure not to press the Home button. Just hold it there until you feel a quick vibration or when you’re prompted to lift your finger.
  • Continue to lift your finger and then rest your finger slowly. Make small adjustments to your finger’s position each time you touch the Home button.
  • If you’re prompted to adjust your grip, hold your iPhone as you normally would when unlocking it and then touch the Home button with the outer areas of your fingertip instead of the center portion that you scanned first.

 

To manage Touch ID settings on your iPhone 7, refer to the following steps:

    • Go to Settings-> Touch ID & Passcode menu. Once you get to this section, you may configure any of the following options based on your preferences.

 

  • To enable or disable Touch ID for Passcode, iTunes & App Store, or Apple Pay, simply toggle the switch next to each of these options as you prefer.
  • To enroll or register more fingerprints, follow the same steps when you register your first fingerprint. You can enroll up to five fingerprints. The next fingerprint recognition process can take slightly longer. Thus, you may need to be a bit patient.
  • To rename a fingerprint, tap on the desired fingerprint and then enter a desired name.
  • To delete a fingerprint, swipe the desired fingerprint.
  • To identify a fingerprint in the list, touch the Home button. Doing so will highlight the matching print briefly.

 

Use Touch ID to unlock your iPhone 7, make purchases with iTunes or Apple Pay

Once you’re fingerprint is registered, you can now start using Touch ID to unlock your iPhone, make purchases or pay for Apple Pay purchases. Instead of entering a passcode, you can use Touch ID to unlock your iPhone. Just press the Home button using the finger you have registered with Touch ID and once it matches the ones stored in the iPhone’s secure domain, access is granted.

To make purchases in iTunes Store, App Store, and iBooks Store using Touch ID on your iPhone 7, follow these steps:

 

  • Go to Settings-> Touch ID & Passcode-> and make sure iTunes & App Store is turned on. Otherwise, go to Settings-> iTunes & App Store and then enable it from there.
  • Next, open the iTunes Store, iBooks Store, or App Store.
  • Tap on the item you want to buy. A Touch ID prompt will appear.
  • To make a purchase, lightly touch the Home button with the registered finger and to authenticate and authorize purchase. Do the same when making Apple Pay purchases in stores, within apps, and on websites in Safari using Touch ID.

 

Apple Pay allows you to make in-store and online purchases with your iPhone. With Touch ID these transactions can be done with much ease and convenient. All you need is a scan of your fingerprint and once when the print matches, credit and debit card purchases should go through.

What to do if you cannot enroll a fingerprint, cannot unlock your iPhone or prompted to enter your passcode when using Touch ID?

There are times when Touch ID doesn’t seem to work as intended on your iPhone 7. Should that happen to you, here are a few workarounds you can try on. Be sure to test the Touch ID after completing each step to determine whether it’s already fixed. Proceed to the next applicable solution, if necessary.

 

  • Verify and ensure that your iPhone 7 runs the latest iOS version. To check the current iOS version or available updates, go to Settings-> General-> Software Update. If an update is available and you would want to proceed, tap the option to Download and Install then follow the onscreen instructions to download and install new iOS update on your device. Be sure to back up your iPhone beforehand for safekeeping purposes.
  • Check and ensure that your fingers and the Home button are clean and dry. If necessary, you can clean the Home button using a clean, lint-free cloth to wipe off any dirt or debris.
  • When positioning your finger, make sure that your finger does not cover the Home button completely. Touch the surrounding metal ring and do not tap too quickly or move your finger around while Touch ID is scanning.
  • If you are using a case or screen protector, make sure it does not cover the Home button or surrounding ring. You can remove the case or screen protector temporarily and then try using the Touch ID again without any of the said accessories.
  • Make sure that iPhone Unlock or iTunes & App Store is enabled on your device. To do so, head over to Settings-> Touch ID & Passcode. If necessary, toggle the switch to enable the feature. Also make sure that you have enrolled one or more fingerprints. Try enrolling a different finger, if necessary.
  • Reboot your iPhone 7 then try to use Touch ID again to unlock it.
